IMPROVED RETAINER FOR WINDOW-SASHES.

To all whom it may concern Be it known that l, J. H. WEEKS,ofPhiladelphia, Pennsylvania, have invented an Improved 'Retainer forWindow-Sashes; and I do hereby declare the following to be a full,clear, and exact description of the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon.

My invention relates to that class of devices which are attached to thesashes of windows for the purpose of retaining them in an elevatedposition; and my invention consists of the combination of a lever havinga knob and a projection, a spring, and a bolt with a lip,

the whole being constructed, applied to a sash,

and arranged for joint action, in the manner described hereinafter, sothat a downward pressure imparted to the knob will move back the rod,release the sash, and permit the saine to fall.

In order to enable others skilled in the art to make and use myinvention,I will now proceed to describe its construction and operation.

On reference to the accompanying drawings, which form a part of thisspecification, Figure lis a side view,`partly in section, of sufficientof a window sash and frame to illus trate my invention 5 and Fig. 2,asection on the line 1 2, Fig. 1.

A is the lower bar of the sash, which slides in the side pieces, B Bf,of the windowframe. Into the barAts a metal box or case, C, covered by aplate, F. (Represented in dotted lines, Fig. l.) Through an opening atone side of the box, near the lower edge, passes a rod, D, on the innerend of which is a lip, 0

the outer end of the rod, when the sash is at its greatest height,projecting into a recess, a, in the side piece B. To a pin, d, securedto the back of the box, is hung a lever, which has two projecting arms,e and c. The end of the lower arm, e, of the lever bears against theinside of the lip c of the rod D, and from the side-of the upper arm,e', projects a pin,f, which passes through a slot in the plate F, and isfurnished at its outer end with a knob or button, G. A spring, lc, isarranged to bear against the inner end of the rod D.

When it is desired to lower the sash, a downward pressure is applied tothe knob G, the arm e being thereby caused to bear against the innerside of the lip c, and force back the rod D, so as to withdraw the outerend of the latter from the recess c. rIhe sash will now descendv by itsown weight, or by thero itinued pressure on the knob.

rlhe sash is raised by applying the press ure to the under side of theknob, and when it has reached the limit of its upward mr tion the end ofthe rod D is brought opposite the depression a, into which itis forcedby the action of the spring k, the sash being thereby securely retainedin its elevated position.

Most oftheretainers for wiudow-sashes heretofore used have been soconstructed as to require that the sash shall be held up with one hand,while the other is used for operating the retaining device. Many ot'these i11- struments are also so complicated that it is a matter ofdifficulty for many persons unacquainted with their construction tooperate them. Such devices are especially objectionable when applied tothe sashes in railwayA cars,vwhore they have frequently to be operatedby those who are not familiar with any kind of retaining mechanism.

It will be seen that in the above-described device the knob willnaturally be seized by any person, in order to either depress or elevatethe sash, and that the motion thus imparted to it will ei'ect thedrawing back or projecting of the rod, and release or secure the sash,.as required.

It will also be seen that but one hand only may be used, the sash b ingsupported by means of the knob without i iterfering in the least withthe action of the spring k, and that the device is simple in itsconstruction, not liable to get out of order, and can be made andapplied to any sash at a slight cost.

I claim as my invention and desire to secure by Letters Patent- Thecombination of the lever E, its knob G and arm or projection c, thespring k, bolt D, and its lip o, the whole being constructed, applied toa sash, and arranged for joint action as and for the purpose herein setforth.

In testimony whereof' I have signed my name to this specification in thepresence of two subscribing witnesses'.
